How to add PEEQ as initial conditions in Abaqus?

26 July 2023 0 634 Report

I want to model a metal with initial plastic strains and stress (stress > yield stress). Stress can be added with prestress. So how to add PEEQ? Or I don't need to add PEEQ, Abaqus will calculate the corresponding PEEQ based on my prestress.
